Simplifying (4x2) + x + -4 = 0 Reorder the terms: -4 + x + (4x2) = 0 Solving -4 + x + (4x2) = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -1 + 0.25x + x2 = 0 Move the constant term to the right: Add '1' to each side of the equation. -1 + 0.25x + 1 + x2 = 0 + 1 Reorder the terms: -1 + 1 + 0.25x + x2 = 0 + 1 Combine like terms: -1 + 1 = 0 0 + 0.25x + x2 = 0 + 1 0.25x + x2 = 0 + 1 Combine like terms: 0 + 1 = 1 0.25x + x2 = 1 The x term is x. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. 0.25x + 0.25 + x2 = 1 + 0.25 Reorder the terms: 0.25 + 0.25x + x2 = 1 + 0.25 Combine like terms: 1 + 0.25 = 1.25 0.25 + 0.25x + x2 = 1.25 Factor a perfect square on the left side: ((x) + 0.5)((x) + 0.5) = 1.25 Calculate the square root of the right side: 1.118033989 Break this problem into two subproblems by setting ((x) + 0.5) equal to 1.118033989 and -1.118033989.Subproblem 1
(x) + 0.5 = 1.118033989 Simplifying (x) + 0.5 = 1.118033989 x + 0.5 = 1.118033989 Reorder the terms: 0.5 + x = 1.118033989 Solving 0.5 + x = 1.118033989 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + x = 1.118033989 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = 1.118033989 + -0.5 x = 1.118033989 + -0.5 Combine like terms: 1.118033989 + -0.5 = 0.618033989 x = 0.618033989 Simplifying x = 0.618033989Subproblem 2
(x) + 0.5 = -1.118033989 Simplifying (x) + 0.5 = -1.118033989 x + 0.5 = -1.118033989 Reorder the terms: 0.5 + x = -1.118033989 Solving 0.5 + x = -1.118033989 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + x = -1.118033989 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = -1.118033989 + -0.5 x = -1.118033989 + -0.5 Combine like terms: -1.118033989 + -0.5 = -1.618033989 x = -1.618033989 Simplifying x = -1.618033989Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.618033989, -1.618033989}
